7. SPECIAL FUNCTION KEYS
Special function keys are simply short cuts to menu screens/options. Further information on the
operation of these function keys is contained in
Section 5.
This section lists Functions that may be programmed to the programmable function keys. Consult
RCA for those functions that have been programmed in to your radio.
7.1. ALARM
The Alarm function key (default F5) is used to put the radio into Emergency Mode. Alarm is
supported in Digital mode only.
Pressing the Alarm key causes the radio to set the emergency flag in transmit voice messaging
and, depending on the radio configuration, optionally enter Transmit/Receive cycle mode. In cycle
mode, the radio will transmit live microphone audio at high gain for the nominated duration and
return to receive mode for the nominated duration.
This cycle will repeat indefinitely or until the radio is turned off and on again.
7.2. ANNOUNCE
To send an Announce call on the channel, press this function key and then use the PTT to send
the call. The next PTT after the Announce will call the default group.
7.3. CHANNEL UP AND DOWN
The current selected Zone’s channel is decremented whenever the key is pressed.
The channel up and down functions are normally assigned to the / function keys. They can be
assigned to other keys if required.
If you are on the first channel and press the key, the channels will wrap around to the last
channel in the current zone.
